The Los Angeles Fire Department was placed on "Emergency Quake Mode," however, an initial survey found little damage. A little after 9 o'clock local time, a spokesperson for the Los Angeles Fire Department, Brian Humphrey, said there appeared to be "no major structural damage, no serious injuries."

The U.S. Geological Survey said the 4.7 quake was located about a mile east of Lennox, CA, and about 10 miles, south, southwest of the Los Angeles Civic Center. It is the largest quake in the area in nearly a year.
